Built around a robust metal body with a corrosion‐resistant finish and a bright red lever handle, it installs easily into straight runs of pipe or hose assemblies. The 1/4" BSP female connection suits common British Standard Pipe fittings used on compressors, sprayers, small plant, generators, and pressure washing setups. Quarter‐turn action gives fast, positive isolation with clear open/closed indication. Supplied with a smooth inline bore to minimise pressure drop. Sized at 1/4 inch (6.35 mm) BSP; note BSP 1/4 has a thread outside diameter of approximately 13.2 mm. Manufacturer Part Number: 850 014.
